Hi! taylover-pei San!
The parameter 0.37 means that cut out detected image by leaving its height (or width) times the padding
.
The code to do it is as follows
for i in range(len(shape) // 2):
x = (padding + mean_face_shape_x[i]) / (2 * padding + 1) * desired_size
y = (padding + mean_face_shape_y[i]) / (2 * padding + 1) * desired_size
If you change the scale of detector, change scale
in first stage detection.
In the mtcnn_detector
, run detection by the scales values.
for scale in scales:
return_boxes = detect_first_stage(img, self.PNets[0], scale, self.threshold[0])
so you should change the calculation method to a good feeling ;)
